Weather Alerts and Warnings for Riverside

Air Quality Alert

Air Quality Alert issued February 1 at 10:35PM PST by NWS San Diego CA
Feb 1, 10:35 PM Feb 3, 12:00 AM
WHAT: The South Coast AQMD has issued a mandatory wood-burning ban
for residents in the South Coast Air Basin. The No-Burn rule bans
burning wood, pellets, and manufactured fire logs in any indoor or
outdoor wood-burning device.

WHERE: The South Coast Air Basin, which includes Orange County and
non-desert portions of Riverside and San Bernardino counties. No-
Burn Day alerts do not apply to areas above 3,000 feet in
elevation, the Coachella Valley, or the High Desert. Homes that
rely on wood as a sole source of heat, low-income households and
those without natural gas service also are exempt from the
requirement.

WHEN: Monday.

IMPACTS: Particles in smoke can get deep into the lungs and cause
health problems (including asthma attacks), increases in emergency
room visits, and hospitalizations. No-Burn Days are needed to
protect public health when fine particle pollution levels are
expected to be high anywhere in the South Coast Air Basin. No-Burn
Days are based on fine particle pollution levels that are
forecasted for an entire 24-hour period, which may not be reflected
in real-time air quality maps.

Run your air conditioner and/or an air purifier and avoid using devices that bring in outside air like a swamp cooler or whole house fan if you have other ways to stay cool. Additional details for this air quality alert are available at www.aqmd.gov/advisory. Information on the South Coast AQMD Check Before You Burn program is available at www.aqmd.gov/cbyb.
